Autumn Across America
Teale, Edwin Way
St. Martins, New York 1956
This book is part of a 4 volume set written over several years where the author and his wife set off on road trips across the country to follow the progression of a season. This was the second volume, and as with the first the general premise is that the author and his wife, both naturalists, write a naturalist biased travelogue as they go around the country. Observations about the land, flora and fauna, weather, etc.. are interspersed with comments on the trip and places and people visited, meals eaten, etc.. which give the entire book a mix of scientific, travel, and history perspectives which works very well.
In Autumn they generally head east to west, starting on Cape Cod and ending in Point Reyes. The route had generally been across the northern tier to Washington, then down the coast, but with some excursions further south.
